A second-minute try from loose-head prop Alex Corbisiero set the tone for a rampaging Lions performance, who scored four tries and trounce their hosts by a record margin.

"We fronted up today and I think the scoreline reflected it and we represented the four countries with pride," Lions skipper Alun Wyn-Jones said after the match.

"We wanted to win the collisions and breakdowns. It was always going to come down to that today. They came back at us in the second half and we came back pretty well."

Corbisiero's opening try was converted by Lee Halfpenny who also bagged four first-half penalties to give the Lions a healthy 19-3 lead moments before the halftime whistle.

James O'Connor's converted try on the stroke of halftime reduced Australia's deficit to nine points and two penalties from Christian Lealiifano early in the second half narrowed the Lions' lead to just three points.

"You always doubt decisions you make, but you have to make those hard calls. I have taken a bit of flack. It was about the boys today and winning the series. It was an outstanding performance. We started well, came under some pressure and bounced back."
